Difference Between 168 And 194 Bulbs

What Is The Wattage Difference Between 168 And 194 Bulbs?

The immediate difference between the two bulbs is their length and base width, with the 168 bulbs standing shorter and having a wedge base with a width of approximately 0.67 inches (17mm). In disparity, the 194 bulb is just immense and as a substitute of about 0.44 inches (11mm).

The wattage range for the 168 and 194 bulbs is the same, generally between 3 and 5 watts. Some specific bulbs may have little extra wattage ratings, but generally, both bulbs supersede specifications.

168 Bulbs Design Explain

168 Bulbs Design Explain

  • The 168 bulb is a small wedge base bulb normally operated in automotive lighting applications such as the dashboard, mechanism grouping, and internal lighting.
  • The design of the 168 bulbs contains a short reflector or plastic tablet that boards a filament wire assembled of tungsten. The bulb is naturally loaded with a fixed gas, such as argon or nitrogen, to support the spread of the filament’s life and enhance the fair outcome’s grade. The filament wire is warmed by an electric current giving via it, which drives it to cast sunshine.
  • The 168 bulb is available in mixed colorings and shine levels, making it fortunate for multiple automotive lighting applications. Its compressed measurement and lower fuel consumption finish it a popular choice for other applications, such as electronic devices, flashlights, and smallish machines.
  • The wedge ground of the 168 bulbs is devised to fit into a socket with a complementary figure and size. The bulb is secured in the socket by two small wires that involve coercion to the flanks of the wedge base, forming a snug and protected linkage.

194 Bulbs Design Explain

194 Bulbs Design Explain

  • The 194 bulb is a small cylindrical incandescent bulb customarily used in automotive applications. It naturally consists of a mirror bulb, a filament, and two metal relations that serve as the bulb’s base.
  • The two metal references at the bulb’s ground are typically made of a copper alloy and are invented to fit into the vehicle’s light spout socket. This design allows the bulb to be easily installed and removed from the vehicle’s golden institution. The contacts are often positioned in a wedge-shaped base, with the more expansive end of the bottom fitting into the socket and the narrower end keeping the bulb
  • The glass bulb of the 194 bulbs is typically straightforward, authorizing the light to pass through unclogged. The filament, part of the bulb that begets light, is generally made of tungsten wire and is curved into a small spring-like figure. When an electrical breeze is handed via the filament, it warms up and casts light.

What Are the Differences?

Bulbs are typical in automobiles, performing as light origins. You uncover them in headlights, sidelights, haze lights, and more. They furthermore reach in nimble in the motorcar interior, for fair provision, and for car signals. Indoor and outdoor bulbs vary. We concentrate on interior bulbs, consequently the 168 vs. 194 bulb discussion. An incorrect premise is the 168 and 194 bulbs are duplicates.

The term is to disprove this falsehood by thoroughly looking at the two bulbs Before peeking at their discrepancies, you should learn they are T10 bulbs, a mini-wedge bulb variety. Keep reading for additional data on the disparities between 168 and 194 bulbs.

168 Bulb 194 Bulb
Ordered for approximately 4.9 watts of power Placed for almost 3.8 watts of energy
  The light result is more colorful than 194 bulbs.   Just more shadowed light result resembled to 168 bulbs
  Ranked for 3 candle energy Ranked for two candle energy
Endures approximately 1500 hours with everyday use The lifespan of most bulbs is about 2500 hours, actually with serious use
Begets better warmness It delivers little more minor heat, though the dissimilarity is not enormous
Primarily noticed in augury sunshine etc Operated for endless lighting
Can be operated at distinct ranks of cleverness Just one style of brilliance delivered

168 Bulbs and 194 Bulbs Compared


Beginning off with the fuel rating of these bulbs, we keep one of the slightest disparities between the two. One hundred sixty-eight bulbs are rated for 4.9 watts, whereas 194 bulbs are ranked for about 3.8 watts.

That isn’t an enormous unlikeness, and it shows in the bulb’s interpretation and light outcome. That said, we can register that 168 bulbs suggest nominally additional useful inner measurement and lighting.


A typical objection many people have obeying 168 bulbs is that they operate a shred hotter than 194 bulbs, which can cause despair for the driver inside while potentially dissolving or damaging helpless pliable parts. The contrast in warmness is not that large between the 2, and both are secure for medium usefulness.

Wear Case

One hundred sixty-eight bulbs are most generally found in warning lights, map lights, glove case lights, etc. The theme is that these bulbs are scheduled to be used in sunlight angled on smallish usually.

On the other writing, 194 bulbs are prepared for steady lighting and are, thus, a more attractive option if you tend to use inner rays for a further protracted course duration.


As anticipated, these two bulbs have a bit of dissimilarity in terms of cleverness. One hundred sixty-eight bulbs are additionally hopeful, ordered for about three candlepower, matched to 2 candlepower on the dimmer 194 bulbs. In a system, this disparity isn’t directly pronounced; however, 168 bulbs completely offer broader scope, which is vital for interior use.


One hundred sixty-eight bulbs last around one thousand and five hundred hours with regular use. But 194 bulbs muff that digit out of the moisture with a whopping 2500 hours of use, even with more weighty loads. This tremendous distinction in longevity is why many somebody chooses 194 bulbs over 168 bulbs for indoor usage.

Levels of Brightness

Another helpful dissimilarity that will make or break either bulb for you is the brightness stations that these bulbs can be utilized. One hundred sixty-eight bulbs are scheduled to be used at distinct cleverness levels.

That indicates if you’re using these bulbs in your gauge cluster, you can dim or illume the light swinging on ambient light positions. One hundred ninety-four bulbs only after one brilliance level, which is a significant weakness when you consider that various stations of brilliance are more adorable and valuable in different conditions.


Understanding bulb specs offers you a shopping godsend, as you know what you want. In the matter of the 168 bulbs vs. 194 bulb message, one of the specs to recall is candlepower, a measure of luminous passion.

The brighter 168 has three candlepower, while 194 has two candlepower. Bulb fuel is an additional parameter to communicate on. The 194 has a more elongated life at 2500 hours, with typical to sober use of the 168 drains at 1500 hours when used regularly.

The two bulbs retain almost equal heat display levels, with the 168 living hotter by a remote margin.168 vs. 194 bulb size comparison delivers you that the two are identical. Both the bulbs have the highest overall measurement of 26.8-millimeters, a light inside measurement of 14.2-millimeters, and a greatest external diameter of 14.2-millimeters.168 vs. 194 v/s. 2825 bulb.

What is the discrepancy? The 2825 bulb is more identical to the 168 bulb, and you may operate them interchangeably due to their brightness. Here we factor in the lumens and the proportions of the light. The 2825 bulb is the considerable radiant, ranked at approximately 41 lumens, and near obeyed by the 168 at 38 lumens, with the 194 maintaining 27 lumens.

What Is the Difference Between a 168 and 194-bulb

In fact, they all have the same base, they’re all made the same with the same incandescent filament – the only difference is the wattage. Depending on the number of the bulb; 194 versus 168, all it does is dictate the amount of wattage the bulb draws. The more wattage the bulb draws, the brighter it is.

161 Bulb VS 168 Bulb

Difference between 161 and 168 bulbs. It all Comes Down to Wattage.

The T10 comes in 194, 168, W5W, 147, 152, 158, 159, 161, 168, 194, 192, 193 – and they all basically look the same. In fact, they all have the same base, they’re all made the same with the same incandescent filament – the only difference is the wattage.
